Abstract (en)
[origin: US2018289362A1] A biopsy needle for collecting a tissue specimen includes an outer cannula that is at least partially received within a handle housing and an inner tube received within the outer cannula and configured to receive a stylet. A snare coil is attached between the inner tube and the outer cannula and is configured to wind down when the inner tube rotates in a first direction relative to the outer cannula and uncoil when the inner tube rotates in a second direction relative to the outer cannula. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.
